Tempus AI CEO Sells $10.5 Million Worth of Shares Amid Ongoing Losses
Eric P. Lefkofsky, the founder-CEO and chairman of Tempus AI (NASDAQ:TEM), sold 250,000 shares of Class A Common Stock for a total value of $10.5 million on July 28, 2026. The transaction was conducted through multiple entities indirectly holding his stake and is part of a pre-scheduled Rule 10b5-1 trading plan established in March 2026. Despite the sale reducing Lefkofsky’s holdings by about 4%, he still owns approximately 6.5 million shares, valued at $279.52 million as of July 28. The stock closed slightly lower on July 29 at $41.55 per share compared to the weighted average sale price of $42.06 and a closing price of $42.90 on the day of the transaction. Tempus AI, which operates in precision medicine with a focus on oncology diagnostics and analytics, reported trailing twelve-month (TTM) revenue of $1.4 billion but remains unprofitable with a net loss of $254.4 million. While insider selling can raise concerns among investors, the structured nature of this transaction suggests it is part of long-term liquidity planning rather than an indication of negative sentiment toward the company or its stock.
